    摘要: The present invention provides processes for preparing normorphinans from N-substituted morphinans. In particular, the invention provides methods for removing the N-substituent from the N-substituted morphinan to from a normorphinan carbamate, and then removing the carbamate functionality from the normorphinan carbamate to form the normorphinan.

    摘要: A system for assaying an eluate for Technetium-99m and Molybdenum-99 content includes an inner ionization chamber including a well configured to receive the eluate, an outer ionization chamber concentric with the inner ionization chamber, and attenuating material positioned between the inner and outer ionization chambers. A computing device is configured to determine a Technetium-99m content of the eluate based on a first current measured in the inner ionization chamber, and determine a Molybdenum-99 content of the eluate based on at least a second current measured in the outer ionization chamber.
